Static Calculation of Load of Buried HDPE Pipes with Profiled Wall and Smooth Pipe Inside [PE]

# 1985 York

Trials to investigate the deformation and buckling behaviour of HDPE pipes with profiled outer wall and smooth bore are reported. Results show that the deformation and stability check can be carried out in the same way as for solid-wall pipes. However, an additional check on circumferential compressive stresses is required for the relatively thin-walled profile. These compressive stresses must be lower than the permissible buckling stress of the profile and the permissible compressive stress of the material.

In order to improve the circular economy of polymers in terms of sustainability and reduced carbon footprint, the increased use of recyclates has become a topic of major importance. Due to their long design lifetimes, pipe applications represent an excellent opportunity to create added value to non-virgin polymers. In...

The Strength of HDPE Pipes for the Renovation of Pipelines by Sliplining

Author(s) : Meldt 1982 York

A method of specifying the HDPE pipes to use in renovation is described. The following factors are considered: flow capacity, stress during insertion into straight and non-straight lines, lifting and buckling forces experienced by the lining while the cavity between it and the old pipe is filled. Four sources of...
